η2-dpndy) (4), and the paddle-wheel complex [W(CO)3]2(μ,η2-dpndy)3 (5). Further treatment of W(CO)3(Me3tach) with 3 generates the tripodal compound W(CO)3[(μ,η2-dpndy)W(CO)3(η2-dpndy)]3 (6). The molecular structures of 2 and 5 have been determined by an X-ray diffraction study.
通过用BuLi和PPh 2 Cl依次处理HC⋮C(CH 2)5 C⋮CH来制备多功能配体双(二苯基膦基)-1,9-壬二炔(1;缩写为dpndy)。化合物1下进行反应以W(CO)4(NCMe)2,得到W(CO)4(η 2 -dpndy)(2),而在反应1和W(CO)3(ME 3转速)(ME 3转速= 1,3,5-三甲基-1,3,5-三氮杂环己烷)产生W(CO)3(η 2 -dpndy)(η 1 -dpndy)(3),[W(CO)3(η 2 -dpndy)] 2(μ,η 2 -dpndy)(4),和桨轮络合物[W(CO)3 ] 2(μ,η 2 -dpndy)3(5)。W(CO)的进一步处理3(ME 3与转速)3生成三脚化合物W(CO)3 [(μ,η 2 -dpndy)W(CO)3(η 2 -dpndy)] 3(6)。2和5的分子结构 由X射线衍射研究确定。
